IMPROVEMENT IN TURIBINE WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of thesame.

v To all whom 'it may concern:

Be it known that I, JESSE NEWLIN, of tle'city and county ofPhiladelphia, in the State of Pennsylvania, have invented a new anduseful Improvement in' Turbine Water-Wheels, of which the following is afull, clear, and exact descriptioix, reference being had to theaccompanying drawings, which make part of this specification, andinwhich- Figure l is avertical central section through myimprovedturbine, f

Figure 2 is a diagram, showing myimproved method of adjusting thebuckets of the wheel when arranged vertically relatively to thecrown-plate; and

Figure 3, a similar diagram, with the buckets inclined to thecrown-plate, and at right angles to the rim of the wheel.

My invention is equally adaptable to that class of turbines in which thewater passes directly through the crowns of the wheel, (calledparallel-flow turbincs,) or to that class in which thewater flowsthrough the Wheel at right angles to this axis; and

The object of my invention is to adapt the wheel to the head of water,4by increasing or diminishing the area of the issues; to which end,

The improvement herein claimed, consists in a novel lmethod of combiningpivoted buckets with adjusting# devices, actuated by a rod movingendwise through the Y arbor of the turbine.

In the accompanying drawings- A -representsthe frame, which supports thestop B on which the arbor O revolves. That portion of the arbor abovethe bottomof the turbine is hollow.

A rod, D, passes down through they tubular arbor,

,and its lower end is slotted to receive cross-arms d,

which support a flanged plate, E.

Inclined loops or slotted brackets, projecting underneath this plate,reeeive`pins i, projecting from the buckets F F, which are pivoted toswing, as shown in v red in figs2 and 3, so as to vary the area of theirdischarge-orifices. v

It well known that with a supply or flow of water insufficient to fillthe discliarging-area of thebuekets completely, turbines fail to developtheir maximum perby my plan, the miller is enabled at all times to ad`just the escape of the water to the supply, and thus secure the fullworking-capacity of the turbine, its advantages are obvious.

The upper end of the arbor C turns in suitable bearings in theflame-work, while the lifting-rod -D terminates in a box, G, beingprovided with ahead or iiange,

d, to sustain it in the box, and yet allow it to revolve freely therein.

A screwed spindle, H, on the upper side of the box, is acted upon by afemale screw, secured in a bandwheel, I, by which means the rod, andconsequently the adjustillg-plate, may'ghe raised or lowered, andthearea of the issues correspondingly varied.

On the left side of iig. l, and in fig. 2, the buckets F are, as shown,pivoted to swing horizontally, while on the opposite side of fig. 1,andin iig. 3, the buckets F are shown as pivoted to play vertically.

In' the latter ease, the water enters the buckets di rectly through thecrown of the wheel, and the flow is parallel to the axis, while in theformer case, the How is from the circumference inward.

It is unnecessary to describe the details of construetion of theturbine, such details being well understood by skilful millwrights, andforming no part of the subject-matter herein claimed.

' What I claim my invention, and desire to secure by Letters Patent, is-

'Ihe combination, with the turbine, of the pivoted buckets,adjusting-plate and lifting-rod, substantially v
